Techniques of Data Reduction for Ground Based Stereo Photographs and Aircraft Recorded Atmospheric Variables

摘要

Data was reduced and analyzed to support studies on the growth and dynamics of cumulus clouds. The photographs and record charts evaluated were supplied by the Cloud Physics Branch, Meteorology Laboratory, Air Force Cambridge Research Laboratory. Measurement techniques were introduced and used to obtain a sequence of measurements for cumulus clouds from stereo ground based photographs. Trajectories, dimensions, and velocities of cloud tufts were obtained from computer processing and graphed. Atmospheric variables and electric fields patterns were determined from oscillograph records of instruments aboard aircraft. The resulting data has been and will be used by Air Force personnel for further analysis and study. (Author)
